Harley Headlights retrofit headlight unit with 8 cm diameter aluminium housing, 12V 35W halogen bulb producing yellow light, electroplated black finish for classic and custom motorcycle builds
Harley Headlights 8 cm Aluminium Housing 12V 35W Halogen Motorcycle Headlamp

This Harley Headlights unit is a dedicated headlamp assembly engineered for motorcycle applications where a classic, round headlight profile is desired. It serves as a functional lighting component and a styling element, constructed from aluminium and designed around a halogen bulb. The product's specifications, including its 12-volt operation, 35-watt consumption, and yellow light output, define its electrical and optical characteristics. Its primary value lies in being a complete, ready-to-install unit for riders undertaking restoration projects, custom builds, or straightforward replacements, offering a specific look defined by its material finish and light colour.
Features and Construction

The headlight is built around its core components: the aluminium housing, the glass lens, and the halogen bulb. This section details the tangible elements that define the product's fit, function, and appearance.
Material and Build
The main body of the headlight is fabricated from cast aluminium, a material selected for its ability to be shaped into a single, complex housing. This process results in a solid unit that houses the bulb holder and provides the structure for the lens rim. The aluminium receives an electroplated black finish, giving the housing its specified colour and surface properties. The lens is made from glass, with options available for clear or yellow-tinted glass depending on the desired final light effect and aesthetic preference.
Size and Practical Fit
The overall dimensions of the aluminium housing are 17 cm tall by 17 cm wide by 15 cm deep, defining the physical space it will occupy on the motorcycle's front end. The critical front-facing measurement is the 8 cm diameter of the lens opening, which dictates the size of the light projection and is a key visual characteristic of the unit. A 10mm mounting screw is supplied, which is the primary point of attachment, meaning installation requires a compatible bracket or mounting point on the motorcycle's frame or forks to accept this fastener.
Uses and Placement

This headlight is designed for vehicular use, specifically on motorcycles. Its application ranges from precise OEM replacement to broader customisation projects, influenced by its electrical specs and style.
Event or Professional Use
For professional bike builders or workshop restorations focusing on a classic or retro motorcycle style, this unit provides a defined component. Its specification of a yellow halogen beam and black aluminium housing offers a particular look that can be integral to a build theme, such as for café racers, bobbers, or vintage-style customs. The fact it is a complete unit with a stated 12V, 35W rating allows builders to plan the electrical system accordingly, knowing the power draw and voltage requirements from the outset.
Everyday Home Use
For the home enthusiast or motorcycle owner performing their own maintenance, this headlight represents a straightforward swap-out part. If an existing headlight on a compatible motorcycle fails or if the owner wishes to change the bike's appearance, this product offers a specific alternative. The available options for lens glass—clear or yellow—allow the rider to choose between a standard white light or the distinctive yellow beam, which can be a personal preference or a style choice for their daily ride.
Benefits and Buying Value

The value of this product is rooted in its stated specifications and construction, which meet the need for a specific type of motorcycle component without requiring modification or additional sourcing of parts.
Reuse and Low Maintenance
As a complete assembly, the headlight unit is designed for long-term installation. The aluminium housing is intended to be durable under standard riding conditions. The halogen bulb is a serviceable part; when it eventually fails, it can be replaced with another standard halogen bulb of the same fitment, meaning the entire housing does not need to be discarded. This repairability is a practical aspect of its design.
Why Choose This Product
This Harley Headlights unit is chosen for its concrete specifications: an 8 cm diameter lens in an aluminium black housing producing a yellow 35W beam. It is selected when these exact attributes are required, whether for authentic period-correct restoration, to achieve a specific custom look, or simply because the rider prefers the yellow light output. It provides a defined solution, removing uncertainty about compatibility and appearance that can come from sourcing individual components separately.
